A lockable glovebox cover unit is configured for mating engagement with a frame mounted on a motorcycle. The unit includes a rigid cover element presenting a front and back. Portions of the back extend outward. A locking apparatus is received through the cover and includes a rotatable latch on the back of the cover element. When the latch is placed in the locked position access to the interior of the glovebox is not possible. A keyhole is formed on the front of the cover element for access to the interior of the glovebox. Additionally, the cover unit may also be removed from the frame when unlocked. The cover element is preferably made of a synthetic resin. In particularly preferred embodiments the cover unit includes a metal flange affixed to lower portions on the back of the cover. The flange is adapted for mating, gripping engagement to the frame.
